Anaphylaxis (Anaphy) is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you're allergic to, such as peanuts or bee stings.
Anaphy is the study of the relationships between people and their environment. It is a holistic approach to understanding how people interact with their environment and how their environment affects their lives. It also includes the study of how people interact with each other and how their interactions affect their lives.
